and shoes. The general object of the invention is to provide an improved organization which, without sacrifice of other utility, will be especially adapted for incorporation in such machines, to the end that the operation of these machines may be better and more easily controlled in important respects, and the machines be better and more readily adapted to the varying requirements of different classes of work.

The invention is herein illustrated as embodied in a machine of the'type commonly known as a loose nailing machine, machines of this type operating to insert individual previously formed fastenings into the work for various purposes in the manufacture of boots and shoes. Such machines, as well as various other fastening inserting machines, are provided with work feeding mechanisms frequently comprising an awl which, in addition to penetrating the work intermittently to form successive fastening receiving openings, operates between fastening insert- I ing operations to feed the work to present a fastening receiving opening in fastening inserting position.

One of the objects of the present invention. is to provide improved means, especially adapted for use in connection with fastening inserting machines of the general type above mentioned, for controlling the extent of movement of certain of the fastening inserting instrumentalities thereof, for example, the awl or other shoe feeding mechanism of such machines, which will be constructed and arranged to permit accurate and ready adjustment without interrupting the operation of the machine, so that the extent of movement of such an instrumentality may be regulated as desired, not only when the machine is idle but also when the machine is being operated.

In the use of fastening inserting machines for inserting fastenings successively in a row parallel to or otherwise definitely related'to a characteristic such as an edge contour of the work and in which an awl is used to penetrate the work to form fastening receiving openings and to feed the work, provision must be made for effecting transverse movement of the shoe feeding means relatively to the direction of shoe feeding movement by reason of the fact that otherwise, unless the edge contour of the work is straight so that the work is fed in a straight line, the openings made by the awl would be progressively offset out of alinement with the fastening inserting means to an extent depending not only upon the amount of turning movement imparted to the work by the operator, but also depending upon the extent of work feeding movement imparted between successive fastening inserting operations.

Another object of the invention is to provide improved means for effecting the required transverse movement of the awl relatively to its direction of feeding movement,

to the end that the lateral adjustment of the awl made necessary by the turning movement of the work, as well as by any substantial adjustment of the extent of work feeding movement, may be readily accomplished.

In accordance with these and other ob jects of the invention, there is provided, in connection with a controlling member for the instrumentality,the extent of movement of which is to be adjusted, a member con structed and arranged to present a partreadily accessible to the operator and adapted to be quickly manipulated by him to change the extent of movement of said instrumentality during the operation of the machine. I provide further a support for the awl mounted for straight line adjustment on the awl bar in a direction transverse to the feeding movement of the awl.

Other objects and features of the invention will be apparent from the following detailed description read in connection with the drawings.

The invention will be described as incorporated in a loose nailing machine of the ters Patent No. 1,030,775, granted on an application of George Goddu, to which Letters Patent reference may be had for detailed description and explanation of various features of the illustrated mechanism, not set forth fully herein. It is to be understood, however, that, although the invention is herein described and illustrated in connection with such particular form of fastening inserting machine, its scope, as will be apparent from the appended claims, is not limited thereto, and that it may have other uses including use in other types of fastening inserting machines. invention in its broadest aspect is applicable not only for the control of the feeding movement of the awl or other feeding instrumentality, but also for the control of the operation of the other instrumentalities of the machine.

Referiing to the drawings:

Figure 1 is a front elevation of the head of a fastening inserting machine of the form described inthe patent above referred to, showing my invention applied thereto;

Fig. 2 is a broken view in perspective of the parts in which my invention is embodied;

Fig. 3 is a detail view showing the means for supporting the fulcrum block in adjusted position; and Fig. 4 is a detail in perspective of the lowerv end of the awl supporting bar.

Similar reference numerals indicate similar parts throughout thev specification and figures of the drawing.

As shown, the fastening inserting or nail driving mechanism comprises a driver bar 24 mounted to reciprocate vertically in a guideway in an upright part 26 of the machine head, and having clamped thereto at its lower end a driver 28. The driver bar I has formed thereon rack teeth 34 which conframe to. feed the work so that the fastening receiving openings come successively beneath the driver bar.

The awl carrying frame is actuated in the direction to feed the stock by a lever 104 connected at one of its ends by an eccentric 106 to the awl carrying frame. Said eccentric may be rotated by the application of a tool to the square head 108 thereof so as to adjust the connection between lever 104 and the awl carrying frame for a pur- Furthermore, the

pose hereinafter set forth. The lever 104 is pivotally mounted on a fulcrum block 110, which is supported by a stud 112 mounted on a slide 114 arranged for vertical movement ina groove 116. in a casting 118 fixed to the main frame 12. The fastening means for said casting comprises a bar 120 having two rods extending transversely from the same at either end thereof and passing through suitable openings in the frame 12 and in said casting. Nuts and washers are provided on the threaded outer ends of said rods.

A slot 122 in the lever 104, elongated in the direction of the length of the lever, receives the fulcrum block. 110 in such manner that the block may be adjusted relatively to the slot. Said lever is provided with a roll 124 adapted to ride in cam slot 126 of the disk cam 128 mounted 'on the shaft 130.

As shown, the shaft 130 is rotated by mechanism substantially like that shown in the patent to Goddu, No. 1,030,775, above referred to, and when rotated operates the awl bar 96 through the connections hereinbefore described.

It will be apparent from the foregoing that, by adjustment of the fulcrum block in the slot 122 of operating lever 104, the extent of feeding movement of the awl 66 may be made greater or less according to whether the fulcrum block is moved upwardly or downwardly in said slot. Such adjustment may be made by moving the slide 114 carrying the fulcrum block 110 upwardly or downwardly in the groove in the casting 118. v I V In order to indicate the position of said slide corresponding, for example, to any particular spacing offastenings, an indexis provided on said casting at one side of said groove.

For the purpose of providing for con venient adjustment of the slide 114, a handle 110 of such form as to be readily grasped by the hand of the operator may be provided.

It is, however, not essential to this invention that the operating means for the slide 7 114 be constructed to be actuated by the hand of the operator. Said operating meansmay be arranged for actuation by the foot or knee or in any other convenient manner.

Means is also provided for maintaining the fulcrum slide 114 in any position of adjustment to which it may be moved. As shown, said means comprises locking plates 134 and 136 mounted on the side of the casting 118 adjacent to the handle member 132. Each of said plates 134 and 136 carries a longer and shorter lug 138 and 140 respectively, between which the head 142 of a rod 144 mounted in a boss 146 extended laterally from handle member 132, and

yieldingly pressed in the direction of the plates by aspring 148, is adapted to be received. The longer lugs 138 are located at the upper and lower ends respectively of the plates and operate as stops to limit the extent of movement of the fulcrum slide 114 by engagement with the head 142 of the rod 144. Each of the plates 134 and 136 is provided with a V-shaped projection 150 adapted to be seated in similarly shaped spaced horizontal grooves in the casting 118. The positions of said grooves thereby determine the points to which the plates may b adjusted. Said plates when adjusted are locked in position by bolts 152, plassing through elongated slots 153 formed in said plates.

In the operation of the mechanism as thus far. described, the locking plates 134, 136 are first properly adjusted and secured by bolts 152. The position of the plate which is engaged with the fulcrum slide 114 determines the spacing of the fastenings at the beginning of the operation. In addition to being operative to produce any desired length of spacing of the fastenings in different pieces of work, this invention may be operated to control the insertion of fastenings in any part of an individual piece of work whereby longer or shorter spacing of the fastenings in that part of the work may be effected. It is very frequently desirable to reinforce certain parts of certain kinds of work such as, for example, the shank portion of a shoe by spacing the fastenings at those parts more closely than at other parts of the work such as, for example, the toe portion of the shoe. In a common use of the illustrated machine, the fastening inserting operation is begun on the shank portion of the shoe, in which case, the fulcrum slide 114 is initially positionedwith the spr ng pressed head 142 seated between lugs 138 and 140 of lower plate 136. In such position of the slide114, the fulcrum block 110 is located relatively close to the point of connection of operating lever 104 and the awl carrying member 98, and at a relatively great distance from roll 124 of said lever operated by cam 128. The feeding movement of the awl is therefore relatively small, causing relatively short spacing of the fastenings. The upper plate preferably is initially adjusted to a position determined by the length of spacing of the fastenings desired at the toe portion of the shoe.

When the driving of the fastenings in the shank portion is completed, and the toe portion of the shoe has arrived within the sphere of action of the fastening inserting means, the fulcrum slide 114 is moved upwardly, the yielding head 142 being thereby disengaged from the lugs on the lower plate, and being moved into position between lugs 138 and 140 of the upper plate where it ings.

operates to lock the fulcrum slide at its upper point of adjustment. When the operation on the toe portion of the shoe is completed and the shank on the other side of the shoe comes within the action of the fas tening inserting means, the handle member 132 is manipulated by the operator to move the fulcrum-slide downwardly to again decrease the extent of spacing of the fasten- It is to be understood that although the operation of the invention has been described with particular reference to an especial mode of procedure, the invention is not to be limited thereby.

As before stated, the character of the spacing of the fastenings at the beginning of the operation is determined by the point of adjustment of the plate with which the fulcrum slide 114 is in looking engagement. The point of adjustment of the other plate will determine theextent of spacing of the fastenings after the manipulation of the fulcrum slide. the plates 134, 136 may be so adjusted as to change the extent of the respective spacings, as the fulcrum slide 114 is moved up and down, while maintaining uniform the variation in spacing efiected by the release of the fulcrum slide from engagement with one plate and the movement of the same into engagement with the other. Said variation in length of spacing may be made less or greater by the adjustment of said plates toward or from each other.

The eccentric 106 may be adjusted when necessary to line up the machine before use It is apparent, therefore,

so as to make'the actual spacing of the fas- 'i ten-ings correspond with that indicated by' the index, or to compensate for wear of the parts for a like purpose. If there were provided no adjustment for wear of the parts other than that of the fulcrum slide rela tively to the index, the index would not of:

wardly and downwardly substantiallybas shown in the Patent No. 1,030,775, aboveireferred to. The lower section 156 has the awl clamped therein and is adjustably attached to the upper section in such manneras to permit the adjustment of the lower section of the awl bar and the awl carried thereby in a direction transverse to the direction of feeding movement of the awl. In the par-' ticular embodiment of my invention illustrated in the drawing, said attaching means consists of teeth 160 and a bolt and slot conneetion conventionally shown. As'pr'eviously stated, said adjustment is so made as to compensate forthe movement of the opening in the work made bythe awl out of the path of the driver. The extent of movement of such opening from the path of the driver depends upon the amount of turning movement of the work. It has been found in practice, for example, that some operators on some kinds of work as, for example, shoes turn the work more abruptly than do other operators at a corresponding point of the WVOIk. The lower section of the awl bar carrying'the awlshould, therefore, be adjusted to suit the particular operator. It has been found further that the extent to which openings made by the awl move from the path of the driver depends upon the frame, work feeding means, a lever for controlling the movement of said work feeding means, a fulcrum for said lever, a member carrying saidfulcrum, means mounted on said frame constructed and arranged to limit the movement of said member to a fixed path, and means connected to said member for ready actuation by the operator while the machine is in operation to adjust said fulcrum in said path.
